1.5.1^[1] is a minor update to Minecraft (Java Edition) released on March 21, 2013,^[2] which mainly fixed issues with low frame rates on certain devices. As the protocol is the same as 1.5, players on 1.5.1 can connect to servers that are running 1.5. While it was not the last update to 1.5, it was the last one before the snapshots of 1.6.1 started.

A pre-release version of 1.5.1 was released on March 19, 2013. The 1.5.1 pre-release was reuploaded on March 20, 2013, to fix a null pointer crash,^[3] and this reupload became the full release of 1.5.1.
